Description

A kind of Sweet-osmanthus black tea and preparation method thereof
Technical field
The present invention relates to a kind of preparation of tealeaves, a kind of black tea and preparation method are especially related to.
Background technique
Sweet osmanthus integrates ornamental and medicinal, records in Compendium of Material Medica: sweet osmanthus, sweet in flavor, pungent, warm-natured, energy warm stomach, Beneficial stomach, cold extermination.Sweet osmanthus has effects that dispersing stagnated hepatoqi, expelling phlegm and arresting coughing and whets the appetite along lung.Xianning,hubei is big well-known throughout the country as five One of sweet osmanthus commodity production base, 2467 squares of hectares of cultivated area produce more than 60 ten thousand kilograms of osmanthus flowers per year, area, yield, Quality is the first in the nation, and is that ideal osmanthus flower tea prepares material.
Jasmine tea is liked because of its pleasant fragrance of a flower and mellow flavour by consumer.Traditional osmanthus flower tea is by tea embryo system Standby, fresh sweet osmanthus, which harvests, tea embryo basement flower, logical flower radiate, continue basement, rocket, dries 7 procedures such as dry again is made.Osmanthus flower tea Processing, temporary no-trump sweet osmanthus and fresh tea leaves rub technology simultaneously, mostly or use traditional processing technology, multiple scenting at present After dry.The osmanthus flower tea technique that this mode makes is cumbersome, and big with flower amount, fragrance is not lasting, and sweet osmanthus sentimental taste is obvious.
Therefore, it is badly in need of a kind of simple process, the sweet osmanthus scented black tea preparation side that at low cost, fragrance fresh degree of fragrance is high and persistence is good Method.
Summary of the invention
In view of this, this method uses fresh tea leaves the purpose of the present invention is to provide a kind of processing method of sweet osmanthus scented black tea Technology is rubbed simultaneously with fresh sweet osmanthus, and simple process is few using flower amount, at low cost;The second object of the present invention is to provide by this Sweet osmanthus scented black tea made from method, sweet osmanthus scented black tea obtained can retain the nutritional ingredient and effect of sweet osmanthus, and fragrance of a flower fresh degree of fragrance Height, fragrance is persistently and flavour harmony is good.
The technical scheme is that
A kind of preparation method of sweet osmanthus scented black tea, comprising the following steps:
(1) tea leaf withering: picking And Development of Tea Shoot is 20~25 DEG C in temperature, and interior is withered to containing under the conditions of humidity is 65~85% Water is 58~65%;
(2) sweet osmanthus prepares: in fine day morning, starting to pick sweet osmanthus after dew disperses completely, removes impurity;
(3) rub: the fresh tea leaves to have withered and fresh sweet osmanthus proportionally being mixed thoroughly, is put into rolling machine and rubs, rub by it is light- Weight-light principle pressurization after sky rubs 30min, pressurizes to the completely flexible appropriateness again of leaf, gradation, rubs to hold tea base, there is tea juice It overflows, tea group is not loose after loosing one's grip, and tea base is in golden yellow;
(4) it ferments: fermenting rubbing leaf made from step (3) and being put into fermenting case, 25~30 DEG C of temperature, humidity 90~94%, hair 3~4h of ferment, leaf color take on a red color, and green gas disappears, and after distributing pure and fresh fresh dense flowers and fruits perfume, stop fermentation;
(5) it is freeze-dried: the tealeaves after fermentation being subjected to gradient increased temperature freeze-drying, in -50 DEG C of pre-freeze 5h, using temperature programming Vacuum freeze drying to moisture is lower than 7%, obtains sweet osmanthus scented black tea.
Preferably, in step (1), the young sprout is simple bud, one leaf of a bud or two leaves and a bud.
Preferably, in step (2), the acquisition sweet osmanthus best time should be 3~5 days in osmanthus fragrans Post flowering, at this time shell It has been fallen off that, the fragrance of sweet osmanthus is most dense.
Preferably, in step (3), fresh tea leaves and fresh sweet osmanthus are proportionally 20~10: 1.
Preferably, in step (3), tealeaves is uniformly mixed with sweet osmanthus before rubbing.
In order to keep polyphenol oxidase (PPO) and the peroxidase (SOD) of tealeaves and sweet osmanthus to have higher activity, preferably , in step (4), fermentation temperature is controlled at 25~30 DEG C, and the reduction speed of enzymatic activity is slower, is conducive to tea polyphenols substance Enzymatic oxidation.
In order to retain more aroma substance of sweet osmanthus, it is preferred that in step (5), by the way of vacuum freeze drying.It is excellent Choosing, in step (5), described program heating be at -50 DEG C of vacuum freeze drying 5h, -50~0 DEG C vacuum freeze drying 5~ 20h, 5~15h of vacuum freeze drying at 0~50 DEG C are dried in vacuo 8~20h at 50 DEG C.
In conclusion the invention has the beneficial effects that: (1) it is rubbed simultaneously using tealeaves and fresh sweet osmanthus, includes tealeaves Object sufficiently merges with sweet osmanthus content and carries out biochemical reaction, combines the Type of aroma of black tea and sweet osmanthus and has both the guarantor of the two Strong effect;(2) sweet osmanthus is added during tea processing in the present invention, compared with traditional scented tea baking, simplifies processing technology, It reduces and is measured with flower, reduce artificial and Material Cost;(3) tea-drying after being fermented using vacuum freeze drying mode Processing can preferably retain various aroma substances, reduce and measured with flower, and the fragrance of product is more rich, stereovision is richer; (4) sweet osmanthus scented black tea obtained, the content and accounting of the flowers and fruits volatile compound such as linalool, ionone significantly mention through the invention It rises, and generates the milk fragrances substances such as valeric acid leaf-alcohol ester.
Method disclosed by the invention is simple, it can be achieved that industrialized production, sweet osmanthus scented black tea fresh degree of fragrance obtained is good and fragrance is dense Yu Chijiu, few Shi Shaogong, reduces cost, has very big application potential and promotional value.
